Madison Jeffries

Madison Jeffries is a Canadian mutant mechanic with the psionic ability to reshape metal, glass, and plastic at will. A Vietnam-era U.S. Army veteran, he eventually joined Canada's Gamma Flight program before rising through the ranks to serve with Alpha Flight.

Madison Jeffries burst onto the Marvel scene in 1983's Alpha Flight #1, a Bronze Age debut courtesy of the legendary John Byrne, and he's been a quietly essential presence in the Marvel Universe ever since. Over four-plus decades and 112 catalog appearances — seven of them collector-recognized key issues — he's proven himself far more than a supporting player, sharing adventures with heavy hitters like Heather Hudson, Vindicator, Walter Langkowski, and Sasquatch along the way. His journey has taken him across some of Marvel's most storied titles, from Alpha Flight to Invincible Iron Man to The Avengers, a breadth that speaks to a character with real staying power. If you haven't explored what Jeffries brings to the table, his long, surprisingly varied history makes him exactly the kind of deep-cut discovery that reminds you why you fell in love with comics in the first place.
